Java中的浮点 shortValue() 方法及示例
Float 类中的shortValue()方法是Java中的内置方法,它在类型转换后返回通过调用对象指定的值作为 short。
语法:
public short shortValue()
返回值:它以short形式返回 FloatObject 的值。
下面的程序说明了Java中的shortValue()方法:
方案一:
Java
// Java code to demonstrate
// Float shortValue() method
class GFG {
public static void main(String[] args)
{
// Float value
Float a = 17.47f;
// wrapping the Float value
// in the wrapper class Float
Float b = new Float(a);
// shortValue of the Float Object
short output = b.shortValue();
// print shorting the output
System.out.println("Short value of "
+ b + " is : " + output);
}
}
Java
// Java code to demonstrate
// Float shortValue() method
class GFG {
public static void main(String[] args)
{
String value = "54.1f";
// wrapping the Float value
// in the wrapper class Float
Float b = new Float(value);
// shortValue of the Float Object
short output = b.shortValue();
// print shorting the output
System.out.println("Short value of "
+ b + " is : " + output);
}
}
输出:
Short value of 17.47 is : 17
方案二:
Java
// Java code to demonstrate
// Float shortValue() method
class GFG {
public static void main(String[] args)
{
String value = "54.1f";
// wrapping the Float value
// in the wrapper class Float
Float b = new Float(value);
// shortValue of the Float Object
short output = b.shortValue();
// print shorting the output
System.out.println("Short value of "
+ b + " is : " + output);
}
}
输出:
Short value of 54.1 is : 54
